Thats a different issue:
In an *expression*, IDL always converts the lower to the higher type in
this order:
STRING<BYTE<(INT|UINT)<(LONG|ULONG)<(LONG64|ULONG64)<FLOAT <DOUBLE<COMPLEX<COMPLEXDBL
before evaluation.
Before we were taking about reading a string and determining the type
(for storing it appropriately).
Note that for proper conversion one of the types has to have the proper
type beforehand:
IDL> print,'1.23' gt '2e-10'
0
IDL> print,1.23 gt 2e-10
1
but:
IDL> print,1 gt '2e-10'
0

Cheers,
marc
